COMBINED HARROW AND CULTIVATOR.

To aZZ whom it may concern:

Be it known that I, FRANK BATEMAN, a citizen of the United States, and aresident of Spring Mills, Camden county, New Jersey, have inventedcertain Improvements in a Go inbined Harrow and Cultivator, of which thefollowing is a specification.

The object of my invention is to so construct a tooth for a combinedharrow and cultivator that the implement can be readily adapted for bestperforming the particular classes of work for which it is intended, andthis object I attain in the manner hereinafter set forth, referencebeing had to the accompanying drawings, in which Figure l is aperspective view of the tooth; Fig. 2, a perspective view of the-holdertherefor; and Figs. 3 to 6, inclusive, side. views, on

a smaller scale, showing the various ways in.

which the tooth is intended to be used.

The tooth A consists of a bar, preferably of steel, Said bar beingdiamond-shaped in crosssection, and being sheared off at an angle fromfront to rear at one end, so as to form a beveled face, a, and sharppoint I), the opposite end of the bar being expanded, sharpened, andotherwise shaped so as to form a cultivator-tooth, d. The holderconsists of a frame, B, having. a recess, f, for the reception of thediamondend a pivot, 9, whereby it is hung to the bar D of the fixedframe of the implement, and at the rear a segmental slot, 6, for thereception of the stem of a bolt, m,whereby the frame may be secured inany desired position. This permits the tooth A to be held either in avertical or in a rearwardly-inclined position, and the tooth is alsoreversible in the h'olderthat is to say, it can be changed end for end,or can be turned so as to bring either the front or back of the tooth inadvance, thus readily adapting the tooth for the proper performance ofits various duties.v

Figs. 3, 4, 5, and 6 show four different ad-' 5 justments of the tooth,Fig. 3 showing the cultivator-tooth d in acting position for cultivatingsmall plants of tobacco, potatoes, 820.,

shaped tooth A, this frame having at the front the tooth in thisposition having the effect of thoroughly pulverizing the soil withoutthrowing it onto the plants. To form a straight diamond-toothed harrowthe tooth A is reversed end for end, as shown in Fig. at, the sharppoint of thetooth being in advance, and to form a smoothing-barrow it issimply necessary to shift the holder B so as 5 5 to rearwardly inclinethe tooth, as Shown in Fig. 5, the sharp point serving to cut and levelthe surface. When the ground contains young plants, it is advisable toreverse the tooth'so as to bring the sheared end or bevel face of thesame to the front, as shown in Fig. 6, there being less risk of injuringthe plants in this case than there would be if the sharp nose or pointof the tooth were in front.

It will be seen that there is in the face of the holder B at each end ofthe slot 12 an angular recess, 11., for the reception of one corner ofthe head of the bolt m, So that the said bolt-head serves to lock theholder in position and pre- 7o vent it from swinging on its pivot underthe influence of strain exerted upon the tooth A.

I do not in this application claim the peculiar form of holder which Ihave shown and described, as various holders may be used for 7 securingmy improved tooth to the frame of the barrow in the different positionswhich it has to assume; but

I claim as my invention- V The-within-described tooth for a combinedharrow and cultivator, said tooth consisting of a bar, diamond-shaped incross-section, sheared at an angle from back to front at one end, andexpanded and otherwise shaped to form a cultivator-tooth at the oppositeend, all substantially as specified.

In testimony whereof Ihave signed my name to this specification in'thepresence of two subscribing witnesses.
